According to statistics from the Department of Labor, there is a 20% chance you will become physically or mentally disabled between the ages of 20 and 60. Clearly, as a result of this disability, your income may be affected either partially or fully. Having a disability insurance is therefore, very important. Unfortunately, you cannot purchase this insurance if you are not employed because there is no income to insure (insurable interest). There are two types of disability insurance available; short term disability and long term disability. ...
Typically, short term disability insurance provides 80-100% wage replacement for a short illness lasting 3 to 6 months. The insurer starts to pay benefits after a short period of disability, sometimes as early 8 days after the onset of a disability. For illnesses longer than 6 months, you need long term disability coverage. Long term disability may provide up to 70-80% of wage replacement. This type of coverage typically covers you until you reach retirement age. In general, these policies start paying benefits after 180 consecutive days of disability.

There are two main types of disability coverage:
Apart from disability insurance, some workers may be covered by Workers' Compensation which provides eligible employees with coverage for work-related injuries and illnesses in accordance with applicable state laws. Workers' Compensation benefits include coverage for medical expenses and, in certain instances, income replacement for time lost from work. Eligibility and benefits vary according to state law. If you experience a work-related injury or illness that extends beyond 180 consecutive days, you may also be eligible to apply for long-term disability benefits through the Social Security Administration. Although Social Security may also provide disability benefits, it requires a 5 month wait after the onset of disability. You also must prove that you can not engage in any gainful employment and prove that the disability is expected to be at least 12 months or is terminal.
Coverage amounts are a percentage of your base salary. If you are employed, you need to find out if, and how much, insurance is already provided by your employer. Consider the tradeoff between the amount of the disability insurance taken and the premium to be paid. In general people protect at least 80% of their income for long term disability. Note that disability insurance cannot cover 100% of your salary due to adverse selection (people intentionally getting disabled and getting a steady stream of salary for many years).
